10. Accessories
10.1 Measuring adapter MA 2
For the easy measurement of photoelectric current for burner adjustment
and/or troubleshooting, we recommend the use of a special measuring
adapter MA2 (order no. 10042.00010).
The MA 2 measuring adapter is connected between the connector of the
photo conductive cell. The measuring cables of the adapter are sufficiently
long and can be directly and easily connected to the amperemeter.
10.2 Knurled-head screw for dismantling the
diaphragm valve
For the easy disassembly of the diaphragm valve from the oil pre-heater,
we recommend the use of a special knurled-head screw (order no.
10023.00026).
10.3 Portable pump tester
For de-aerating the intake pipe as well as for measuring the injection /
intake pressure of the pump, we recommend the instruments from our
portable pump tester (order no. 10042.00001).
It includes:
1 Case coated with foamed material
10042.00008
2 Pressure gauge (0 - 25 bar) 10042.00002
3 Vacuum gauge (-1 - 0 bar 10042.00003
4 Flexible pressure gauge extension with
1/8” screw-in nipple 10042.00004
5 De-aeration device 1/8" with shut-off 10042.00005
6 Reducing adaptor with 8 x 2mm O-ring 10042.00006
7 Reducing adaptor for pressure gauge
with 8 x 2mm O-ring 10042.00007
10.4 Intake silencer
For operation dependent on ambient air, the protective cover at the blower
inlet can be replaced by a intake air silencer which is available as an
accessory (order no. 10003.00167). The sound-reducing internal shape in
combination with the noise-absorbing lining of the intake silencer allows
for the effective reduction of the intake air noise. Due to its flat design, the
silencer can also be used when the hood is installed. The intake silencer
can be installed in the factory or using the conversion kit (order no.
10003.00167) mentioned below.
It includes:
1 Cylinder head screw with SW4 hexagon socket
similar to DIN 912 M4x50 10023.00187
2 Intake silencer 10014.00129
3 Insulating foam, inside 10044.00026
4 Insulating foam, outside 10044.00027
10.5 Sliding flange with additional O-ring sealing
In order to meet utmost requirements regarding odour escaping from the
interface between burner and heat generator, we recommend the use of
a sliding flange connection with additional O-ring sealing. In order to
achieve utmost tightness, the standard flat sealing for the boiler is
supplemented by an additional O-ring sealing. The O-ring sealing can be
installed in the factory or using the conversion kit (order no. 10003.00172)
mentioned below.
The conversion kit includes:
1 Sliding flange for burner 10002.00114
2 Hexagon nut DIN 934 M8 10023.00002
3 Sliding flange S1 for boiler 10002.00141
4 O-ring 10006.00108
5 Countersunk screw DIN 965 M3x5 10023.00043
6 Retaining ring sealing 10004.00328
7 Sealing for KS sliding flange 10006.00003
8 Cylinder screw DIN 7984 M8x13 10023.00063
9 Cylinder screw DIN 7984 M8x30 10023.00008
10 Disk DIN 125 8.4A 10023.00020
11 Sealing for BS sliding flange 10006.00007
12 Hexagon nut DIN 934 M8 10023.00002
13 Cylinder screw DIN 7984 M8x30 10023.00008
14 Disk DIN 125 8.4A 10023.00020
